"When you arrive in Buttercup Close*, drive to the end of the road (which looks like a dead end) and turn left into a small car park. A car clamp/parking fine system is in operation in this car park, so stay with your car and phone me on 0208 xxx xxx and I will bring the typewriter to you. Sorry if this sounds like a strange set-up but it would be a disaster if you picked up a £45 car parking fine for the sake of an old typewriter! Do you have a rough idea of what time you will arrive?"
